Description

Technical Field

[0001] The utility model relates to power plant condenser cleaning equipment, in particular to an ejector anti-loosening device. Background Art

[0002] The condenser of a power plant is prone to scaling and clogging, so the plate holes of the condenser need to be cleaned frequently. Currently, the cleaning device that is commonly used is similar to the application number: CN201820570973.2, and the name is: Detachable condenser chemical cleaning robot device, which cleans the plate holes of the condenser one by one by moving.

[0003] However, during this process, it was discovered that the injector at the front end of the cleaning robot had densely distributed nozzles, which could easily collide with scale and become loose during movement. The reason for this was that the original injector was directly screwed onto the bracket and lacked additional protection design to prevent loosening.

[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0005] The utility model aims to address the deficiencies of the prior art and thus provide an injector anti-loosening device for solving the problem that the injector is easily loosened due to collision.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an ejector anti-loosening device, comprising a nozzle mother pipe, a nozzle and an anti-loosening structure;

[0007] A row of mounting holes is distributed on the injection surface of the nozzle mother pipe, and internal threads are arranged in the mounting holes;

[0008] The tail end of the nozzle is threadedly matched with the mounting hole, and a fastening bolt is arranged in the middle of the nozzle;

[0009] The anti-loosening structure includes a stabilizing frame fixed to one side of the injection surface of the nozzle main pipe, the height of the stabilizing frame exceeds or is equal to the outer end surface of the fastening bolt, and the stabilizing frame abuts against the side of the nozzle or the fastening bolt.

[0010] Based on the above, the injection surface of a single nozzle mother pipe is provided with a complete stabilizing frame, and the stabilizing frame is an integrally formed stabilizing frame.

[0011] Based on the above, the injection surface of the nozzle mother pipe is an arc surface or a plane, and the stabilizing frame is fixed to the injection surface of the nozzle mother pipe by welding or by locking and fixing it by a locking mechanism.

[0012] Based on the above, two sets of screw slider mechanisms are arranged on the rear side of the nozzle mother pipe, the sliders in the screw slider mechanisms are fixed to the nozzle mother pipe, and the screws in the screw slider mechanisms are fixed to the condenser orifice plate to constrain the travel accuracy of the nozzle mother pipe.

[0013] Based on the above, a multi-link swing arm type water inlet pipe is installed at the rear end water inlet of the nozzle mother pipe.

[0014] The utility model has substantial features and progress compared to the prior art. Specifically, the utility model improves the installation method of the nozzle, connects with the nozzle mother pipe in a threaded manner, and then adds a fastening bolt as a supporting component of the nozzle to prevent it from loosening.

[0015] In addition, a stabilizing frame is added based on the entire nozzle structure. The stabilizing frame is used as a supporting component for all nozzles to prevent the nozzle ends from being subjected to force. As a side supporting structure of the nozzle, it effectively prevents the nozzle from shaking, further improves its stability, and ultimately prevents it from loosening.

[0019] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0020] like Figure 1 and Figure 2 As shown, an ejector anti-loosening device comprises a nozzle main pipe 1, a nozzle 2 and an anti-loosening structure.

[0021] A row of mounting holes is distributed on the injection surface of the nozzle mother pipe 1, and internal threads are arranged in the mounting holes;

[0022] The tail end of the nozzle 2 is threadedly matched with the mounting hole, and a fastening bolt 4 is arranged in the middle of the nozzle;

[0023] The anti-loosening structure includes a stabilizing frame 3 fixed to one side of the injection surface of the nozzle main tube 1, the height of the stabilizing frame 3 exceeds or is equal to the outer end surface of the fastening bolt 4, and the stabilizing frame 3 abuts against the side of the nozzle 2 or the fastening bolt 3.

[0024] The injection surface of a single nozzle main pipe 1 is provided with a complete stabilizing frame 3, and the stabilizing frame 3 is an integrally formed stabilizing frame.

[0025] The injection surface of the nozzle mother pipe 1 is an arc surface or a plane, and the stabilizing frame 3 is fixed to the injection surface of the nozzle mother pipe by welding or by locking and fixing through a locking mechanism.

[0026] Two sets of screw slider mechanisms 5 are arranged on the rear side of the nozzle main pipe 1, the slider 51 in the screw slider mechanism 5 is fixed to the nozzle main pipe 1, the screw 52 in the screw slider mechanism 5 is fixed to the condenser orifice plate 6 to constrain the movement accuracy of the nozzle main pipe 1, and a multi-link swing arm type water inlet pipe 7 is installed at the rear end water inlet of the nozzle main pipe 1.

[0027] Working principle description:

[0028] The nozzle main pipe 1 is driven by the screw slider mechanism 5 to perform reciprocating motion from top to bottom. During this process, the swing arm water inlet pipe 7 injects cleaning liquid into the nozzle main pipe 7, and the cleaning liquid is distributed from the nozzle main pipe to each nozzle. The nozzle passes through each plate hole in turn to flush the plate hole and remove dirt.

[0029] In this process, if the dirt protrudes from the end of the plate hole and collides with the nozzle, the fastening bolts 4 and the stabilizing frame 3 play a role in stabilizing the nozzle 2 to prevent the nozzle from loosening.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
